I have a 24 Savage 22/410 barrel that is basically without any finish that I believe dates to '60 or so. Doesn't have the scope groove. Bought for a project that never happened. It has the sights, but most all small parts have been removed. 22 bore is pretty and bright and the 410 bore shines except for a short dull area ahead of the chamber. Don't know whether it's lack of manuf polishing or erosion. Most of the 410 barrel is bright. $30 and I'll ship.
PM for more pics or questions.
